Specification of Letters Patent.

Application filed December 9, 1914. Serial No. 876,270.

To all whom it may concern:

Be it known that I, HENRY C. SNYDER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Internal-Combus'tion-Engine Charge-Forming Apparatus, of which the following is a specification. My invention relatesto improvements in charge forming apparatuses for internal combustion engines.

An important object of the invention is to provide means of the above mentioned character for thoroughly atomizing and mixing a liquid fuel, preferably crude or heavy oil, and water, and subsequently sup-- plying the mixture to the cylinder or cylinders of the engine.

A further object of the invention is to' provide means of the above mentioned character, which is simple in construction, reliable in operation, and convenient in use.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a partof this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of an engine, showing my apparatus installed thereon, and, Fig. 2 isa central longitudinal sectional view with the apparatus removed.

In the drawings, wherein for'the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the cylinder or an internal combustion engine of any well known or preferred type having a piston (not shown) reciproeating therein. This cylinder has the usual water jacket, designated at 6. 7

The numeral 7 designates a fuel holding tank, to which the liquid fuel, preferably heavy or crude oil, is supplied through, a pipe 8, such supply being effected by any suitable means.

The numeral 9 designates my improved force-feed pump, as a whole, which is rigidly attached to the cylinder 5 by any suitable means. This force-feed pump comprises a body portion or cylinder 10, within which is mounted to reciprocate a plunger 11, carried by a reciprocatory plunger-rod 12, operatin throu h a stufiing box 13 having screw-t reade engagement with the forward end of the cylinder 10, as shown.

1 leads into the water A compressible and expansible coil spring 15 surrounds the plunger'rod 12 and engages at one end with the stufling box 13 and at its outer end a sleeve 16, rigidly attached to the rod 12. The spring 15 thus serves to move the plunger 11 upon the for- .ward suction stroke. The plunger-rod 12 is moved rearwardly upon the compression stroke by a swinging crank 17, towhich the rod 12 is pivoted, as shown at 18". The crank 17 has operative connection with the crank shaft of the engine, and is swung thereby in properly timed order. It is to be understood that the plunger-rod 12 may be moved rearwardly by connection or engagement with any movable part of the engine, such as a cam or the like.

Connected with the oil holding receptacle or tank 7 is an oil feed pipe 18, connected with one arm of a mixing chamber 19. This mixing chamber is connected with the rear end of the cylinder 10.

The numeral 20 designates an inwardly opening check valve, held seated by a spring 21 and regulating the passage of oil i'nto the mixing chamber and-preventing backflow of fluid or gases into the pipe 18. The upper end of the spring engages an atomizer or perforated plate 22 whereby the oil is sprayed or atomized upon entering the mixing chamber 19. Connected with "the rear end of the mixing chamber 19 is a tubular-extension 23, leading into the same. At its forward end the tubular-extension 23 carries a valve-guide tube 24, within which is arranged an inwardly opening check-valve 25, normally held seated by a spring 26,

engaging a transverse pin 27 attached to" thetube 24. This check-valve permits of the flow of fluid into the mixing chamber 19, but positively prevents the passage of the same in a reverse direction into the tube 23. Connected with the tubular-extension 23 between its ends is a water supply pipe 28, which is preferably jacket 6, to receive water therefrom, while the water may be obtained from any other source. A draincock 29 is connected with the pipe 28, as shown. Arranged within the tubular-extension 23 and having screw-threaded engagement therewith is an adjustable needle valve 30, the inner end of which is adapted to seat adjacent the outlet end of the pipe 28, thus regulating the passage of water into the tubular-extension 23. 1

connected with and Connected with the mixing chamber 19, preferably near and opposite the discharge end of the pipe 18, is a fuel feeding pipe 31, preferably having a check-valve 32 con nected therein, allowing of the free passage of the gaseousmixture to the cylinder or cylinders of the engine, but preventing backfiow of the same. Disposed within the intake end of the pipe 31 is a tubular perforated atomizer. 33 held stationary therein by suitable means, and serving to 'atomize or more finely divide the mixture passing therethrough, prior to its entrance into the cylinder of the engine.

In the operation of the engine, upon the rear or compressed stroke of the piston of the engine the plunger 11 is moved forwardly, creating a substantial vacuum within the mixing chamber 19, whereby the proper amounts of oil and water are drawn into the mixing chamber. The oil is sprayed or atomized by passing through the perforated atomizer or plate 22 and becomes intimately mixed with the water, such mixture being forced through the atomizer 33 and into the pipe 31, to be supplied to the cylinder of the engine, upon the out or power stroke of the piston, the plunger 11 moving rearwardly upon its compression stroke when the piston moves forwardly upon its power stroke.

It is obvious that the apparatus may be used in connection with both two and four cycle engines, the operation of the plunger 11 being of course properly timed with respect' to the operation of the piston, of the engine.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub joined claim. 7

Having thus described the invention, I claim Apparatus for supplying a gaseous mixture of oil and water to the cylinder of an internal combustion engine, comprising. a mixing chamber, a plunger mounted to reciprocate therein and operated by a movable part of the engine, a check valve controlled oil supply conduit leading into one side of the mixing chamber, an atomizing device arranged within the oil supply conduit, a check valve controlled water supply conduit leading into the end of the mixing chamber at substantially a right angle to the oil supply conduit, a manually operated adjustable valve to control the passage of the water through the water supply conduit, a fuel supply conduit leading into the opposite side of the mixing chamber at substantially a right angle to the water supply conduit and connected with the cylinder of the engine, and an atomizing device arranged within the fuel supply pipe.

In testimony whereof I aifix my signature in presence of two witnesses.

HENRY C. SNYDER.
